APPARATUS FOR MAKING PLUMBERSTRAPS.

SPECIFICATION forming part of Letters Patent No. 356,258, dated January 18, 1887.

Application filed August 23, 1875).

To all whom it may concern.-

Be it known that I, JOHN MGcLosKEY, of of the city, county, and State of New York, have invented certain Improvements in the Manufacture of Soft-Metal Traps, of which the following is a specification.

This invention relates to an apparatus for forming seamless lead plumbers traps, in which the lead is forced through an annular die at a greater speed at one side thereof than the other.

The object of the invention is to simplify the construction of dies of this character.

Figure l is a side view, Fig. 2 a plan view, and Fig.3 a centrallongitudinal sectional view,

of a machine embraced in my invention. Fig.

4 is atransverse sectional view of same on a plane at right angles to Fig. 3, and taken in line or a: of Fig. 2. Fig. 5 is a perspective view of the trap made by the use of mysaid invention.

The annular die comprises a hollow ringshaped bed-die, A, and a hollow cylindrical core, B. The bed-die A is attached to and forms a part of the body of the structure, in which is a reservoir, -D, for the molten lead. This reservoir is inclosed within an outer furnace, J, and elevated above the bottom thereof. The core B extends through the body and through the reservoir therein to the bottom of the furnace. This core is cylindrical from its lower end to a point at or near the interior of the reservoir, and from said point within the reservoir it is flattened or reduced on its opposite sides to a point near its upper end, forming tapering partitions or webs B, which divide the chamber 0 between the bed-die and the core into two parts, which are semicircular or arc-shaped in horizontal section. The core above said webs is reduced indiameter throughout its entire circumference, and is provided at its extreme upper end with a small lip or flange, s, which constitutes a part of the die proper. The core is also provided at opposite sides, between the webs, near the upper ends of the latter, with horizontal partitions a, which divide the chamber 0 into a lower part, a, and an upper part, b, said partitions a being provided with grooves or ports b,which establish communication between the upper and lower parts of said chamber, and through which the molten metal is forced toward the 'die proper. The ports b are adapted to be closed to a greater or less degree by screw-rods G G, whichare passed through the bed-die A on opposite sides thereof, their inner ends projecting into the chamber 0 at points opposite the grooves or ports I), and serving as valves. These valves maybe actuated by levers c c. The core B is hollow throughout its length and open at both ends, and a water-outlet pipe, 6, 'is'fitted closely within said core, being removable therefrom, and extends from the top to the bottom thereof. This pipe is provided at its upper end with a chamber, H, which rests on the upper end of the core and serves to cool the same when the dies are in use, water being supplied thereto by means of an inletpipe, f, of smaller diameter than the pipe 6, inserted in said pipe 6 concentric therewith, forming an annular passage, cl, between the said pipes, through which the water escapes 'from said cap. The water may be supplied from a tank, 9, connectedto said inlet-pipef, and in its passage through the cap it chills the core B to a point below the melting-point of lead.

' \Vhen it is desired to remove the core B for any cause,the pipe 6 maybe readily drawn out from the core and the core lifted out of the beddie.

Secured upon the outer wall, A, of the annular die A B, at its top, is an annular tube or hollow ring, I, concentric andin contact with said outer wall, A, said hollow tube or ring forming a passage for water or other cooling medium from the tank or reservoir h to the outlet i, where it is discharged, the cooling medium so passing through said ring I reducing its temperature, and the ring in turn, by contact, reducing the temperature of the outer wall, A,'at the mouth of the annular die to a point below that at which lead solidifies. This ring I is hinged to the bed-die A, whereby it may be readily swung off from the latter when desired. The lead is poured into the receiver D in a molten condition, it being ofcourse desirable that it should be in that condition in which it may be moved through the receiver with the least expenditure of power, and yet be solid when it issues from the die A B. The action of the plunger E therefore forces the heated metal through the receiver D toward the annular die A B, the heated metal passing through the parts a a of the chamber 0, and then through the passages b I), in greater or less volume through one passage or the other, and consequently upon one side or the other of the partition B, and, asa still further consequence, in greater volume or with greater velocity at one or the other of the opposite sides of the annular die A B, the pipe being of course turned or curved in a direction away from that side of the die A B from which the greatest portion ofthe metal issues, or, in other words, that side at which the metal issues with the greatest rapidity or greatest volume, so that by manipulating the valves G G to admit a greater quantity of the metal first upon one side of the partition B and then upon the other or opposite side of the said partition the soft metal issuing in tubular form through the annular die A B is caused to assume the shape of an S-trap, the two streams uniting in the upper part, b, of the chamber C, below the mouth of the die. The walls of the trap or curved tube thus formed will be of uniform thickness at the inner and outer sides of the bends or curves. The degree of curvature is of course proportioned to the relative rapidity of the two streams passing from the receiver D to the two opposite parts of the chamber 0 above the passages b I), and thence to the inn nular die A B, where it issues in the form of a pipe of greater or less curvature and with solid or seamless walls, the outer surfaces of which are more or less marked with longitudinal striations from end to end of the trap, which latter is thus distinguished from other traps by its peculiar appearance.

Heat is applied by any suitable means to the soft-metal receiver D, to maintain the same at the temperature most advantageous in the practice of the invention.

J represents the furnace, of brick or other suitable material, built around the machine to hold the burning fuel, it such be usedforheating the receiver and adjacent parts.

' \Vhat I claim as my invention is-- 1. The combination, substantially as set forth, of a hollow bed-die, a removable tubular core inserted in the bed-die, a removable 5o water-exhaust pipe fitted closely within said core, and provided with an enlarged chamber at its upper end resting on the top of said core, and a removable watersupply pipe of smaller diameter concentric with the exhaustpipe and opening thereinto.

2. The combination, substantially as set forth, of an annular bed-die and a hinged ring-shaped cooling-pipe secured thereto.

3. The combination of a reservoir, a hollow 5o bed-die attached thereto, a core, B, extending through said reservoir and bed-die, said core being reduced at its upper end and also on opposite sides between the mouth of said die and said reservoir, and provided with horizontal J OHN MCCLOSKEY.
